摘要
为了增强TiO_(2)的光催化效果,采用机械研磨法制备了金属有机框架UiO-66衍生的TiO_(2)/Cu_(x)O复合材料,运用了X射线衍射(XRD)、傅里叶红外光谱(FTIR)等对其结构进行表征,并以罗丹明B(RhB)为目标降解物进行光催化降解实验,探讨了催化剂用量、污染物的初始浓度等因素的影响。结果表明:在可见光的照射下,将0.1 g的UiO-66/TiO_(2)/Cu_(x)O催化剂加入到10 mg/L RhB溶液中时,催化剂的催化效果最佳,其对RhB的降解率为97.5%。同时,该催化剂可以应用于其他染料,具有一定的普适性。
To enhance the photocatalytic effect of TiO_(2),a composite material of TiO_(2)/Cu_(x)O derived from metal-organic framework UiO-66 was prepared using mechanical grinding.The structure of this material was characterized by X-ray diffraction(XRD)and Fourier transform infrared spectroscopy(FTIR).Photocatalytic degradation experiments were conducted with rhodamine B(RhB)as the target pollutant to investigate the effects of catalyst dosage and initial pollutant concentration.The results showed that under visible light irradiation,when 0.1 g of the UiO-66/TiO_(2)/Cu_(x)O catalyst was added to a 10 mg/L RhB solution,the catalytic efficiency was optimal,achieving a degradation rate of 97.5%for RhB.Moreover,this catalyst can be applied to other dyes,demonstrating a certain degree of versatility.
